A centre support was welded onto the left pipe and secured with the original Z3 rubber mount. The two centre pipes were joined by a rather nice bar bracket. I have to paint inside the side shape, the exhaust inners and the end bracket in heat resistant matt black paint yet but you get the idea. So the moment of truth arrived. Removing 4 silencers did the trick...it’s loud enough now but has a very deep growl with endless popping and crackling on the overrun. I would even say I prefer the sound to the original Ferrari. Perfect. Very happy customer. So the cost of all this? Remember the tailpipes took three hours to make and two more hours to finish the whole system. This system in future will cost you £585. You will have to wait four weeks though as Matt is in great demand, but worth every penny. Come and see it / hear it at Stoneleigh 2016.
